BYD releases its 5th-gen DM technology with a range of 2100km


On May 28th, BYD released its 5th-gen DM (dual-module) technology. At the press conference, Wang Chuanfu, Chairman and President of BYD stated that the fifth generation DM technology will achieve a power loss fuel consumption of 2.9L/100km, a comprehensive range of 2100km, and an engine thermal efficiency of 46.06%. The Seal 06, equipped with the fifth generation DM technology, has a fuel consumption of 2.9L/100km under NEDC conditions, 10.7kWh/100km under CLTC conditions, and an acceleration of 7.5 seconds from 0-100km/h.

The fifth generation DM technology is based on the fourth generation DM technology, which achieves a maximum power of 74 kW and a maximum torque of 126 N · m for a 1.5L plug-in hybrid engine; Equipped with 10.08kWh and 15.87kWh plug-in hybrid dedicated power blade batteries; The EHS hybrid system EHS120 has a maximum power of 120 kW and a maximum torque of 210 Nm, EHS160 has a maximum power of 160 kW and a maximum torque of 260 Nm; The 12V lithium iron phosphate small battery has the same lifespan as the entire vehicle, achieving lead-free.

The engine adopts a maximum compression ratio of 16 ultra-high, equipped with a high roll flow airway, intelligent combustion system, intelligent electronic injection system, pre catalyst intake EGR, intelligent split cooling, and intelligent variable lubrication system.

The comprehensive operating efficiency of the EHS hybrid system is 92%, with an efficiency increase of 5% and a power density of 75.47kW/L, with an increase of 15.5%. The energy density of the plug-in hybrid blade battery is 115wh/kg, an increase of 15.9%; Discharge rate of 16C, increased by 33%; Feedback rate of 5C, increased by 20.3%; Ultimate safety and uniform temperature.

BYD SEAL 06 2024

In terms of charging, AC slow charging has been upgraded from 3.3kW to 6.6kW, reducing charging time by 60%; DC fast charging SOC 30% -80% only takes 21 minutes, although the charging time is 36% shorter; External discharge upgraded from 3.3kW to 6kW.

12V lithium iron phosphate small battery, the world’s first mass-produced device, reduces weight and says goodbye to battery replacement for life. The fifth generation thermal management architecture has been elevated to the level of overall architecture, with front-end thermal management, cockpit thermal management, and battery thermal management. High temperature energy consumption can be saved by 10%, and low temperature energy consumption can be saved by 8%. The new second-generation battery pulse self heating can achieve self heating during charging, driving, and parking, with a 60% increase in heating speed. In terms of cabin thermal management, the efficiency of the compressor has been improved, and the cabin temperature control rate is faster.
